LOUIS WILPUTI'E, OF NEW ROCHELLE, NEW YORK, ASSIGNOR OF TWO-THIRDS TO ALICE A. WILPUTTE, 0F NEW ROGHELL E, NEW YORK.

COKE QUENCHING AND HANDLING APPARATUS.

To all 1071 cm it may concern:

Be it known that 1, Louis "WILrU'r'rn, a citizen of the United States, and resident of New Rochelle, in the county of estchester and State of New York, have invented certain new and useful Improvementsin Coke Quenching and Handling Apparatus, of which the following is a specifi cation. 7

The general object of my present invention is to provide simple and effective means for receiving and quenching the hot coke V discharged from retort coke ovens and,

after the coke is quenched, for transporting it away from the receiving and quenching apparatus.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, however, and the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described a preferred embodiment of my invention.

Of the drawings:

Figure l is a transverse section of a byproduct coke oven battery;

Fig. 2 is a similar section of a portion of the apparatus shown in F ig. 1 but taken on a larger scale; l V

Fig. 3 is a plan View of the battery; and

Fig. f is a plan view of a portion of the apparatus of Fig. 3 on a larger scale than the last mentioned figure.

In the drawings I have illustrated the use of my invention in connection with a byproduct coke oven battery A of conventional type. The battery is formed with horizontal coking chambers A, extending transversely to the length of the battery and provided at their ends with doors A At the coke or discharge side of the battery there is provided a platform or bench A running lengthwise of the battery and having its upper surface flush with the bottoms of coking chamber A. At its outer edge the bench A merges into an inclined coke receiving wharf F which may be a reinforced concrete structure, preferably having its upper side faced with cast iron plates F. At the lower edge of the inclined wharf F are pillar walls F and F running lengthwise of the battery spaced apart to form a chamber 0 prefer- Speeification of Letters Patent.

ably formed at its bottom with a narrow drain trough or channel 0. As shown the lower edge of the wharf F is supported by the wall F and the wall F is more remote ironi the battery. A series of gates G extend longitudinally along the lower edge of the wharf F, and in its closed position,

these gates prevents the coke on the adjacent portion of the wharf F from sliding off. As shown each gate is connected by hinge pivots G to brackets G which extend from the tageously the gates are provided with counter weights G to facilitate their operation by a workman standing on a'platform J.

Thecoke wharf stops short of the wall F thus providing a slot like opening 0 in the top of the chamber 0 across which the brackets Gr extend. To bridge this gap when coke is being discharged from the wharf a series of movable plates or bridge members H are provided. As shown there is one of these bridge members for each gate G. Each bridge memberas shown is connected by pivots H to the corresponding brackets G so that it may turn back and forth between the dotted and full line positions shown in Fig. 2. In its dotted lineposition each bridge H forms an extension of the coke wharf extending across the opening 0 and the top of the wall F Each bridge member H is provided with an operating handle H by means of which the 9 bridge member may be moved between its two positions by a workman on the platform J.

Advantageously each bridge member H is so pivoted that it is gravity held in either ofthe two positions into which it may be adjusted. The coke passing from the wharf F across a bridge member H, when this bridge member and the corresponding gate G are adjusted into the positions shown in dotted lines in Fig. 2, is discharged onto a conveyer J shown as a belt conveyor running lengthwise of the battery and serving to convey the coke received by it to a screening, carloading, or other receiving station 2 which in the closed position.

' shown in full lines in Figs. 2 and 3, each of for the quenched coke. r'ldvant-ageously a coke feeder l of known type is provided to directly receive the coke passing off the wharf and distribute it uniformly onto the conveyor J. The conveyor J is located between the platform J and the wall F and the coke feeder 1 is movable along a track way to position it first adjacent one gate G and t ien another according to conditions.

Running lengthwise of the battery, adjacent the lower edge of the wharf is an elevated platform or wharf M on which an operator may stand while quenching coke resting on the wharf 1 K represents a pipe supplying water for the coke quenching op eration and L represents a flexible hose for manipulation by the operator on the plat-- form M. A. series of these pipes L may be permanently connected each through a cut off valve. to the pipe K at suitable intervals along the length of the battery, or a pipe K may be provided with valved connections for the ready attachment of a single hose pipe ll which may be thus connected to the pipe K first at one point and then at another. al; the end of the battery a sump (lit is provided into which the drain channel O at the bottom of the chamber empties. Above the platform or bench A there is provided a tr-' l E extending longitudinally of the battery from which is suspended a coke guide E of known type.

In operation when the charge in one of the chambers A is fully coked, the corresponding doors B1 are removed and the charge of coke is pushed out of the coking chamber through the guide E and onto the wharf F by the pusher ram C of a pusher machine D which may be of any well known type. As the coke is pushed through the guide E it distributes itself in a tolerably uniform layer it on the top of the wharf F adjacent the mouth of the coking chamber A being discharged provided the inclination of the wharf is but slightly in excess of the angle required to permit the coke to slide off the wharf. At this time the gates at the lower edge of the adjacent portion of the wharf are closed. The charge of coke is next quenched while on the wharf by discharging water onto it from the pipe K. Any surplus water not vaporized by heat of the coke, which is red hot when pushed onto the wharf F drains off the wharf and into the chamber U, the corresponding bridge members H being then in their full line positions shown in Fig. 2. The water thus discharged into the chamber Q falls to the bottom of the latter and is carried out of the chamber through the channel O. The channel O is preferably made narrow as shown, so that the velocity of the water will be great enough to car y away any coke breeze carried into the chamber 0 with the quenching water.

nose r53 Advantageously vent openings F are formed in the wall F so that steam and vapor rising from the water in the chain er 0 may escape in large measure through these ports to the space beneath the wharf i rather than out through such portions of the opening 0 as may be open.

ll ith the apparatus described the coke may be quenched practically as soon as pushed. thus avoiding any such delay in the quenching operation as is normally involved when the usual quenching car is provided for receiving the hot coke and transporting it to a quenching station at the end of the ba tery. The coke pushed onto the inclined wharf spreads out into a tolerably uniform and relatively thin layer thus facilitating the rapid and uniform quenching of the coke with a minimum of water. The provision of the drainage chamber 0 receiving excess water. between the lower edge of the coke wharf proper and the convey-1r 5 with the adjustable bridge 1 embers T rl eliminates all )OSSllJllll'V of this excess water silashine on the conveyor or running into the trench in ."1

which the conveyer will normally be located. It will be understood that in practice immediately adjacent ovens are discharged at intervals of some hours, so that when any one oven is pushed there will normally be no coke lying on the wha i F in the vicinity of the oven b discharged. The coke H app 'atus disclosed is relatively inen ensive to onstruct and economical iii the ground space required for its installation.

While in accordance with the provisions of the statutes, 1 have illustrated and described the best form of embodiment in my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of apparatus disclos d without departing from the spirit of my invention as set forth in the appended claims and that in some cases certain features of my invention may be used to advantage without a corresponding use of other features.

Having now described my invention, what I claim as new and desire to secure by Let tcrs Patent, is:

1. The combination with an inclined coke quenching wharf of a wall adjacent the lower edge of the wharf, but separated there from by a slot like space, gate members movable into and out of the position in which they prevent coke from sliding off the wharf, and bridge members movable from one position in which they form extensions of the wharf projecting beyond said wall into a second position in which they permit the ready passage of excess quenching water running off said wharf through said space.

2. The combination with an inclined coke quenching wharf of a wall adjacent the lower edge of the wharf, but separated therefrom by a'slot like space, gate members movable into and out of the position in which they prevent coke from sliding off the wharf, and bridge members hinged to swing from one position in which they form extensions of the wharf projecting beyond said wall into a second position in which they permit the ready passage of excess quenching water running off said wharf through said space.

3. The combination with a battery of horizontal coke ovens, of an inclined coke wharf at one side of the battery, a coke conveyer running along the lower edge of the wharf, means regulating the passage of coke from said wharf onto said conveyer and a drainage channel adjacent the conveyer on the battery side of the latter adapted to receive coke quenching water running off the lower edge of the Wharf.

l. The combination with a battery of horizontal coke ovens, of an inclined coke wharf at one side of the battery, a coke conveyer running along the lower edge of the wharf, means regulating the passage of coke from said wharf onto said belt, a drainage channel adjacent the conveyer on the battery side of the latter, one side wall of which is closer to the conveyer than is the edge of the wharf, and members movable from one position in which they form extensions of the coke wharf projecting beyond the drainage channel into another position in which they permitquenching water running off the wharf to pass into said drainage channel.

5. The combination with a battery of horizontal coke ovens, of an inclined coke wharf at one side of the battery, a coke conveyer running along the lower edge of the wharf, means regulating, the passage of coke from said wharf onto said belt, a drainage channel adjacent the conveyer on the battery side of the latter, one side wall of which is closer to the conveyer than is the edge of the wharf, members movable from one position in which they form extensions of the coke wharf projecting beyond the drainage channel into another position in which they permit quenching water running off the wharf to pass into said drainage channel; a platform running along the lower edge of the wharf and quenching water supply means operable from said platform.

6. The combination with a battery of horizontal coke ovens, of an inclined coke wharf at one side of the battery, a coke conveyer running along the lower edge of the wharf, means regulating the passage of the coke from said wharf onto said conveyer, and a drainage channel adjacent the conveyer on the battery side of the latter adapted to receive coke quenching water running off the lower edge of the wharf, said channel being restricted at its bottom.
